Cannot read property 'on' of undefined

[jojost1]

Getting this error since the latest update, in two different homes, on startup.

[jojost1]

Also: it reports '0 accessories' and just deleted my motion sensor..

Powering off the Bridge does not give any errors in the Homebridge window.

[ebaauw]

Did you specify the bridge as host In config.json? Does it still have the same IP address?

Could you please list the output of homebridge -D?

[jojost1]

@ebaauw I did, and it still has. Output:

[2017-4-18 15:22:14] [Hue] 192.168.1.4: hue bridge request #1: ok

[ebaauw]

Please list the full debug output, incl. version numbers, requests, etc.

It would seem Homebridge-hue did at least get its name from your bridge...

Whoops sorry @ebaauw, here's everything:

Thanks, @jojost1.

That narrows down where the Cannot read property 'on' of undefined error message comes from, but, frankly, I have no clue what's causing it. I didn't change that part of the code in v0.3.15. What version where you on before the update?

Also: it reports '0 accessories' and just deleted my motion sensor..
Powering off the Bridge does not give any errors in the Homebridge window.

These are consequences of the first error.

My best guess is a somehow corrupted installation. Some longshots:

• Did you update homebridge-hue through npm? Could you retry

  sudo npm -g install homebridge-hue

• Did you update homebridge to v0.4.19?
• Does homebridge-hue report the same error when it's the only plugin enabled in config.json?
• Is there a reason why you run node v7.7.4? Could you try node v.6.10.2?

[jojost1]

Thanks for the quick response!

What version where you on before the update?

v0.3.14 if I'm correct.

Did you update homebridge-hue through npm? Could you retry...

Did that and tried it again, didn't help :(

Did you update homebridge to v0.4.19?

I did, before updating homebridge-hue.

Does homebridge-hue report the same error when it's the only plugin enabled in config.json?

Bit difficult to test right now. I have to say I did notice the same exact error in my other home, but there I still had my dimmer switch & tap in HomeKit.
Similarities between both setups: I was setting up homebridge-iTunes, which works. Might be that, but that's pretty weird if the case. Maybe you could test it?

Is there a reason why you run node v7.7.4? Could you try node v.6.10.2?

No specific reason. How to 'downgrade' to stable? Can try that.

Thanks!

v0.3.14 if I'm correct.

And re-installing v0.3.14 gets rid of the error?

I have to say I did notice the same exact error in my other home

"Other home" as in another Hue bridge, another installation of homebridge on a another machine?

but there I still had my dimmer switch & tap in HomeKit.

That would be because you killed homebridge in time? If it's the same error, homebridge would run without homebridge-hue exposing anything, causing HomeKit to delete the accessories.

[jojost1]

And re-installing v0.3.14 gets rid of the error?

Nope, it looks like I get the error with v0.3.14/15/17.

I have to say I did notice the same exact error in my other home
"Other home" as in another Hue bridge, another installation of homebridge on a another machine?

Yes, another Bridge, another installation of homebridge, on a completely different Mac. Only common denominator I think is the installation of homebridge-iTunes I was messing around with. Homebridge-hue works on the other Mac right now, but that might be because I deleted homebridge-iTunes there.. I think it is likely that plugin causes problems, is that possible?

See above, I think the plugin exposed the accessories after uninstalling homebridge-iTunes and I don't think I get the error right now (in the other home, my own home is still not working!), sorry I'm unclear ;) Thanks.

Sadly, yes. They override Characteristic.prototype.updateValue(), which is scary at best. To make it worse, they break it by failing to return the characteristic for chaining. homebridge-hue tries to register an event handler on the return value of updateValue(), which now is undefined and no longer contains a property (method) on.
